If you answer 42x42,the answer is
1 764 arrays.
Not counting rotations, there are 4.
You can make five arrays from the number 48
You cannot sort arrays by other arrays; that wouldn't make sense, anyway.
Well, honey, the number of arrays you can make out of 20 really depends on how you slice it. Technically, you can make 20 arrays of size 1, 10 arrays of size 2, 5 arrays of size 4, or 1 array of size 20. So, you've got options, darling. Just pick your poison and get slicing!

4 (or eight if you count transposed arrays as being different).
The number of arrays (or subsets) that can be formed from a set of 42 elements is determined by the formula (2^n), where (n) is the number of elements in the set. Therefore, for 42 elements, the number of possible arrays is (2^{42}), which equals 4,398,046,511,104. This includes all possible combinations, including the empty set and the full set itself.

Your question makes no sense.
1*422*21 3*146*7

Oh, isn't that a happy little question! With 7 elements, you can create many arrays by arranging them in different orders. The number of different arrays you can make out of 7 elements is 5040. Just imagine all the beautiful possibilities waiting to be painted on your canvas of creativity!
Oh, dude, you can make arrays with 15 like 1x15, 3x5, and 5x3. It's like, the possibilities are endless... well, not really, but you get the point. So, yeah, those are the arrays you can make with 15.
